uipopovercontroller

问题 I'm trying to use UIImagePickerController to grab a photo from the users Photos on their iPhone / iPad. This code works just fine for iPhone, but when I run it on iPad, the debugger gives me the message "Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible.". I'm very new to Objective-C, so I'm unsure of whats causing this, I do not dealloc anything and I have ARC turned on. Here is my code:

问题 I've (along with many others) have noticed that Apple changed the appearance of the popover controller to use a "slider" window rather than the usual "popover" tableview that I've used. While I'm okay with the new appearance, like others I'm having issues with the swipe gesture that is introduced: iOS 5.1 swipe gesture hijacked by UISplitViewController - how to avoid? The fix for this seems to be to set the split view controller method "presentWithGesture" to "NO." UISplitViewController

问题 I have a UIPopoverController that contains a UITableViewController within a UINavigationController. Whenever a cell in this table view is pressed, I push yet another UITableViewController to my navigation Controller. I want to set the height of my second table view (let's say to 200) and adjust the size of the popover accordingly. I therefore first set the table view frame in viewDidAppear:(BOOL)animated and then call setPopoverContentSize:(CGSize)size animated:(BOOL)animated . Both heights

问题 I'm looking to present a UIPopoverController from a button on a UICollectionViewCell. So far, everything is created ok, but the popover isn't visible. Is there a special way of doing this? The code works if I display it from anything else other than a collection view cell. The following code is in the UICollectionViewCell subclass. if (_infoPopover == nil) { UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; GameInfoViewController *gameInfoVC =

问题 I have a UIPopoverController containing a UITableView . The popover is resized in its view controller's -viewDidAppear function to fit the contents of the table. While the popover resizes properly, its arrow is usually no longer pointing at the original CGRect . Is there a way to force the popover to reposition itself after a resize so that its arrow is pointing at its intended target? EDIT: I can't set the size of the popover in -viewDidLoad since the table view does not load its data until

问题 I have a MKMapView (also a UIPopoverControllerDelegate) with Annotations. This MapView has, in the MKTestMapView.h file, a UIPopoverController* popoverController defined in the @interface and a @property (nonatomic, retain) UIPopoverController* popoverController; defined outside of the @interface section. This controller is @synthesized in the MKTestMapView.m file and it is released in the - (void)dealloc section. The Annotations in this MapView have rightCalloutAccessoryView s defined to the

问题 I am creating an application for the iPad, and I want to show an UIPopoverController with an arrow pointing to the detail disclosure button for the row it belongs to. I want to do this in the tableView:accessoryButtonTappedForRowWithIndexPath: method. Currently I have this, with a dummy CGRect : - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath { // Dismiss in the case it shows itself somewhere else [addFeedPopup

问题 Is it posible to present a keyboard the way is shown when you set a passcode for your ipad? 回答1: Unfortunately no, But what i did to replicate this was, built a bunch of buttons like a keyboard inside my passcode view using interface builder. Then linked each button to a command that would change the text field. - (IBAction) button9_clicked:(id) sender{ if ([self textField:theTextField shouldChangeCharactersInRange:range replacementString:@"9"]){ self.theTextField.text=[self.theTextField.text
